Rough translation of fanaccount from Chinese in Goguma couple bar @ Baidu.
Most of them described how pretty Hyun is and how handsome Yong is (I will just skip this part and translation the part regarding the interaction between them.)

In “Spy” store (3rd floor), they sell rainbow boots. Hyun went inside and tried lots of boots. Yong recommended about those boots. Eventually, he picked purple boots, asked Hyun to try them on, and paid for them.

After shopping for boots, Yong saw a white hat inside the store and put it on Hyun’s head. Hyun made some weird noise and tried to scare Yong. Yong grabbed her arm and and bursted out laughing. No idea why they were so happy. They kept laughing.

They looked so sweet while picking boots. It made me have bursting cheek again.

They went to the restaurant in the 6th floor. No one can get close to them. Just watched them far away.
They kept talking, laughing, and eating meals. They talked non-stop even the filming stopped.

In the 3rd floor, Hyun helped Yong with his coat and this time Yong helped Hyun with her coat. It was so sweet.

Suddenly, Yong went to downstairs alone and Hyun still waited in the restaurant. Later Yong came back and left with Hyun.

It turned out that Yong left his wallet in the 3rd floor and went back to find it. KeKeKe. Cute Yong.

“They talked non-stop even the filming stopped.” << wow this fact makes me feel giddy!
I even jump from my bed and quickly re-post this translation! XD
Can I assume that woori YongSeo is really real now..? 😀

I think it’s understandable cause they had to talk about next shooting and the next action and YongHwa is talkative person. No wonder they were having conversation. As for Seohyun, Seh doesn’t seem as talkactive person so I’m questioning now, maybe Seohyun is faking herself ?
Some fanaccounts made by the shipper fans can not be trusted 100% because of their 100% biased feeling.
